DRIVING-GEAR FOR GOVERNORS- l Patented Sept. 11, 1906.

Application filed December 28, 1905. Serial No. 298,691.

To al whom it may concern:

Be it known that I, FRITZ REIOHENBACH, a subject of the German Emperor, and a resident of Charlottenburg, Berlin, Germany, have invented certain new and useful Improvements Relating to Driving Gear for Governors, of which the following is a specification.

This invention has for its objectv to prevent the vibrations, and especially the distortions, of the lay or valve-operating shaft by which the governor is driven being transmitted to the governor. This is obtained by a tubular shaft slipped over the lay-shaft, said tubular shaft bearing the driving-wheels for the governor at its one end and being joined with the lay-shaft at its other end as near as possible to the driving-wheels of the layshaft.

The driving-gear is illustrated on the accompanying drawing by a vertical transverse section through the gearing, the engine being shown in side elevation.

In the drawing anneXed,,A designates the engine, which is of the usual construction.

.9 is the lay-shaft, and 1' is the tubular shaft, which is slipped over it. The wheels is and 7c, gearing with or driving the governor c, are

orne at one end of the tube 1", the other end of which is joined in any suitable manner with the lay-shaft s at a point as near to the driving worm-wheel d of the lay-shaft as possible. The lay-shaft is adapted to operate the valve mechanism in the usual manner,

this valve mechanism not being shown, as it is of well-known construction. The end of 1 the tubular shaft to which gear is is secured is journaled in a bearing 8, supported in a convenient part of the engine-frame. It will be observed that the employment of the supplemental tubular shaft (which is supported out of contact or only in loose contact with the lay-shaft, as shown) prevents practically all the distortions and vibrations of shaft affecting the accuracy of the speedgoverning devices. 4

Without limiting myself tothe eXact construction and arrangements of parts herein shown and described, what I claim as my invention, and desire to secure by United States Letters Patent, is

1. The combination of a driving-shaft and a gear thereon for driving it, of a tubular shaft enveloping the driving-shaft and connected rigidly thereto at one end near said gear, a bearing for the other end of this tubular shaft, a driven shaft, and gears connecting the driven shaft to said tubular shaft.

2. The combination of a driving-shaft, means for driving said shaft, a tubular shaft embracing the driving-shaft and attached at one end thereto near the driving means, a gear on the tubular shaft near its other end, a driven shaft, and means for driving the driven shaft from the tubular shaft.

In witness whereof I have hereunto set my hand in presence of two witnesses.

FRITZ REIOHENBACH.
